电厂余热在潘集选煤厂的综合利用可行性分析

Feasibility analysis of comprehensive utilization of waste heat steam from power plants in Panji Coal Preparation Plant

以潘集选煤厂为例,总结了传统供暖方式及煤泥烘干工艺的潜在问题,分析了电厂余热蒸汽替代燃煤锅炉进行供暖和生产的可行性。分析认为:潘集选煤厂如利用电厂蒸汽进行供暖和煤泥烘干,工程总投资3898.74万元,可减少燃煤锅炉运行费用634.3万元/t,可减排烟尘280t/a、二氧化硫40t/a、氮氧化物60t/a。

Taking Panji Coal Preparation Plant as an example,potential problems of traditional heating methods and slime drying processes were summarized.The feasibility of substituting waste heat steam from power plants for coal-fired boiler for heating and production was analyzed.It is concluded that using steam instead of coal-fired boilers needed an investment of 38.98 million yuan,but would reduce 63.433 million yuan operation cost for coal-fired boilers and 280 t smoke,40 t SO 2 and 60 t NO x every year.
